With this module you can enable feature that will block possibility to use voucher codes when cart will contain products that have dropped price (on sale product with discount). Customer will see notification about that. It will be possible to use voucher codes in cart only if products that are there are not on sale.
Please note that this module disables usage of voucher codes in cart if there is at least one discounted product. This is the workflow of this addon.
The main and most important feature of this PrestaShop module is a possibility to disable usage of voucher codes when cart will contain products that are currently "on sale". This means that it will not be possible to use voucher code for products that already have a discount. Sadly speaking PrestaShop by default does not have this feature. But no worries - this module solved the problem in a really quick and handy way.
